Abstract

In an information processing device, when a positional information acquiring unit acquires positional information calculated from GPS signals and the like, a movement area setting unit sets a movement area with a size corresponding to a distance between a current location and a destination. When the positional information acquiring unit acquires positional information indicating a current location after setting this movement area, a judgment unit judges whether the positional information is within the movement area. Then, as a result of this judgment, in a case of being within the movement area, a display control unit executes display control of a display unit so as to display on a map the positional information, and in a case of being outside of the movement area, so as not to display on the map the positional information.

This bus 14 also is connected with IO interface 15.

IO interface 15 is connected with display part 16, storage part 17, input part 18, Department of Communication Force 19, sensor section 20.

Display part 16 is made of display, is used for showing the information of regulation.About the information of the regulation that is shown in display part 16, such as the map that comprises the current location that shows the user who is determined by CPU11 and the destination that sets etc.

Dynamic RAM) storage part 17 is by hard disk or DRAM(Dynamic Random Access Memory: the formation such as, storage are used for the various programs such as program of the processing that regulation CPU11 carries out etc.

And storage part 17 is also suitably stored CPU11 and is carried out the needed data of various processing etc.

Input part 18 consists of the input operation that accepted user carries out by various buttons and the touch-screen etc. of being located at display part 16.

The input operation that input part 18 is accepted is provided for CPU11, then carries out corresponding processing in CPU11.

As an example, accepted at input part 18 in the situation of rolling operation of the map that is shown in display part 16, CPU11 control display section 16 makes map scroll.

In addition, accepted at input part 18 in the situation of amplifieroperation of the map that is shown in display part 16, CPU11 control display section 16 makes to amplify and shows map.

Department of Communication Force 19 has for example corresponding with gps signal gps antenna 191, receives the gps signal with satellite from a plurality of GPS by gps antenna.

The gps signal that Department of Communication Force 19 receives is provided for CPU11(positional information obtaining section 111), when the positional information (for example coordinate on the map) of the current location of calculating expression signal conditioning package 1, use.

In addition, Department of Communication Force 19 is not limited to receive gps signal, also can receive other wireless signal.

That is, Department of Communication Force 19 for example can receive the wireless signal that sends from the access point that arranges as long as receiving the wireless signal of the current location that can calculate signal conditioning package 1 namely is enough to the street, and gps signal is the one example only.

Sensor section 20 is the sensor devices that detect the various states such as the inclination of signal conditioning package 1 and acceleration, and it constitutes and comprises Magnetic Sensor 201 and acceleration transducer 202.

Magnetic Sensor 201 has MI element (the magnetism impedor: Magneto-Impedance element) that for example impedance changes according to the change of external magnetic field, use 3 axles (X, Y, the Z) composition of this MI element testing earth magnetism, and the data of its testing result of output expression.

At this, by using 3 axle compositions of Magnetic Sensor 201 detected earth magnetism, can determine signal conditioning package 1 current towards.

Acceleration transducer 202 has the testing agency of piezoelectric electro resistance type or capacitance type, uses 3 axles (X, Y, the Z) composition of this testing agency's sense acceleration, and the data of its testing result of output expression.

At this, by the acceleration of the acceleration transducer 202 detected X compositions vibration period corresponding to the vertical direction of signal conditioning package 1, the Y composition is corresponding to the vibration period of the horizontal direction of signal conditioning package 1, the Z composition is corresponding to the vibration period of the direct of travel of signal conditioning package 1, therefore by being carried out by 3 axle compositions of acceleration transducer 202 detected acceleration integration and being used, can roughly determine the displacement of signal conditioning package 1.

For example, CPU11 calculates the moving direction of signal conditioning package 1 according to the sensor values of Magnetic Sensor 201, calculate the displacement of signal conditioning package 1 according to the sensor values of acceleration transducer 202, can calculate positional information thus, and replace the location computing based on gps signal.

Fig. 2 is the FBD (function block diagram) of carrying out the functional structure that navigation processes in the functional structure of this signal conditioning package 1 of expression, and this navigation is processed for the user is directed to the destination from current location.

Process in the situation that signal conditioning package 1 is carried out navigation, CPU11 plays a role as positional information obtaining section 111, destination setting section 112, sphere of action configuration part 113, detection unit 114 and display control unit 115.

Wherein, the user is being provided in the service of cartographic information, except the service that processing is finished by signal conditioning package 1 monomer, also have by carrying out the service of communicating by letter processing being finished of provisioning information by signal conditioning package 1 with other device (for example server).

For example, in the signal conditioning package 1 as vehicle navigator, by use the cartographic information of storing in the hard disk of self, signal conditioning package 1 monomer can provide cartographic information to the user.

On the other hand, in the signal conditioning package 1 as portable phone, common storing map information in server in advance, according to the request of accepting from the user, server sends the cartographic information corresponding to signal conditioning package 1, provides cartographic information to the user thus.

About this point, in the present embodiment, can carry out navigation by signal conditioning package 1 monomer and process, also can process by communicated to carry out navigation by not shown server and signal conditioning package 1.

In addition, process the computing that also server is put rules into practice in the situation that communicate to carry out navigation by signal conditioning package 1 and server.

As an example, processing of carrying out the location computing according to gps signal etc. also can be carried out by server, rather than signal conditioning package 1.

About the processing that server is carried out, can suitably set according to the processing power of signal conditioning package 1 or the network performance between signal conditioning package 1 and the server etc.

Therefore, in the following description, so-called " obtaining " comprises that signal conditioning package 1 obtains the result of self computing and the operation result that signal conditioning package 1 is obtained the server of having accepted the computing request.

Positional information obtaining section 111 is according to the gps signal of being supplied with by Department of Communication Force 19, obtains the positional information (for example coordinate) on the map of position (current location) of current time of expression signal conditioning package 1.

Wherein, about obtaining of current location, can obtain by the location computing of the regulation of the gps signal of known usefulness more than at least 3.

In addition, obtaining of positional information obtaining section 111 location information can regularly carrying out arbitrarily, for example can be carried out obtaining of positional information in timing or the time interval according to the rules of the request of having accepted the user by input part 18.

And positional information obtaining section 111 also can obtain the location precision of the precision of expression location computing in the lump when obtaining the positional information of current location.

About the location precision, Dop value (the Dilution of Precision: dilution of precision) that can adopt the configuration status according to gps satellite to calculate.

The positional information that positional information obtaining section 111 obtains and location precision are temporarily stored in storage part 17.

Destination setting section 112 is according to the input operation of accepting from the user by input part 18, and the set positions that the user is expected is the destination.

Positional information (for example coordinate) on the map of the destination that expression destination setting section 112 sets is temporarily stored in storage part 17.

Wherein, the setting of destination can adopt any means to carry out, such as the place name on the map of user input etc. being set as the destination.

In addition, also the place name of accepting from the user by the menu screens such as complete list of place name etc. can be set as the destination.

About this point, the destination setting section 112 of present embodiment can also carry out the setting of destination according to user's rolling operation or amplifieroperation except adopting these arbitrarily the method.

The figure of the setting step of Fig. 3 destination that to be destination setting section 112 carry out according to user's rolling operation or amplifieroperation.

In addition, in Fig. 3 A, Fig. 3 B, Fig. 3 C, spider lable represents destination P1.

At this moment, the spider lable of white is to carry out illustratedly for the ease of easily understanding, and is not presented on the display part 16 of actual signal conditioning package 1.

As user during in map retrieval destination, has the tendency that map scroll in the demonstration of making shows the map around the destination.

With reference to Fig. 3 A, among the map M1 in being shown in display part 16, in the situation that the user is set as the destination with destination P1, the user carries out rolling operation so that destination P1 arrival point center of graph.

When the map of display part 16 rolls according to this rolling operation, shown in Fig. 3 B, show the map M2 that destination P1 is shown in approximate centre at display part 16.

, have this tendency, that is, in the rolling of map, the user uses the less map of reduced scale for fear of miscellaneous operation.

On the other hand, have this tendency, namely in the less map of reduced scale because the details on the map are unclear, thereby with after map scroll is around the destination, the user amplifies the map around the destination.

Consequently, after near the map M2 the user is shown in approximate centre to destination P1 carries out amplifieroperation, shown in Fig. 3 C, be shown in display part 16 with amplifying the map M3 that shows around the P1 of destination.

The core of the map M3 that destination setting section 112 will be exaggerated after rolling like this is set as destination P1.

Thus, the user is the automatically setting destination with map scroll and amplification only, can improve convenience.

In addition, in the situation that destination setting section 112 automatic settings the destination, preferably shown in the black spider lable among Fig. 3 C, the destination P1 that sets is expressed on map M3.

Thus, notify the user to set destination P1 according to rolling operation or amplifieroperation that user itself carries out, can prevent faulty operation.

At this moment, the user map M3 that is exaggerated demonstration carried out rolling operation and the situation of the fine setting having carried out showing under, the core of the map after preferably will finely tuning is reset to destination P1.

In above-described destination setting section 112, the core that is exaggerated the map M3 of demonstration is set as destination P1, but destination P1 is not limited to core, also can set according to the mode of user's amplifieroperation.

For example, in the display part 16 of the touch-screen form that is known in recent years, (representative manner is to contact touch-screen under the state with the first finger and the second finger closure in the linearly movement of touch part by making two points on the touch-screen, then mobile under the state that the first finger and second finger of closure are opened), the information of map etc. is amplified.

Owing to having near the tendency the destination that the touch of two points when amplifying partly is the user, thereby destination setting section 112 also can be set as destination P1 with the intersection point of two straight lines of mobile route that represents respectively the touch part of these two points.

Specifically, destination setting section 112 accepts input part 18(touch-screen) mobile route (track) of detected touch part, and determine the intersection point of this mobile route, set thus destination P1.

In this case, preferably will express in map be used to the destination P1 that notifies the user, and preferably again establish destination P1 by later fine setting.

Turn back to Fig. 2, the positional information of current location and the positional information of destination are read from storage part 17 in sphere of action configuration part 113, and obtain the sphere of action that sets according to these positional informations.

The sphere of action that sphere of action configuration part 113 is obtained is temporarily stored in storage part 17, and offers detection unit 114.

In the location computing of using the wireless signals such as gps signal, sometimes between the position of reality and the position that determines, produce error.

About this point, in the present embodiment, even also be that the scope that the user can allow is set as sphere of action with producing error, and cover the position that exceeds this action scope and determine.

That is, so-called sphere of action refers to the scope that the user can allow when producing error.

Thus, the positional information that next time obtains in positional information obtaining section 111, to exceed in the situation of positional information of the sphere of action that obtains according to the positional information of current location sphere of action configuration part 113, the demonstration that can not carry out based on the positional information that exceeds this action scope at display part 16.

In other words, the positional information of the current location that obtains in positional information obtaining section 111, to exceed in the situation according to the positional information of the sphere of action that obtains in the positional information that obtains before the positional information of this current location of sphere of action configuration part 113, the demonstration that can not carry out based on the positional information that exceeds this action scope at display part 16.

At this, the user is being directed to from current location the navigation Service of destination, the scope of the error that the user can allow is different from the distance of destination according to current location.

As an example, in the situation that far away from the current location distance to destination, namely be enough to as long as understand the roughly direction of destination, and in the situation that nearer from the current location distance to destination, then need the detailed position relationship of current location and destination.

Therefore, preferably carry out the setting of sphere of action according to the distance of the positional information of the positional information of current location and destination.

The figure of one example of Fig. 4 A, Fig. 4 B sphere of action that to be expression sphere of action configuration part 113 obtain according to the positional information of the positional information of current location and destination.

Fig. 4 A is illustrated in the sphere of action T1 that the distance L 1 of current location P2 and destination P1 obtains when far away.

Sphere of action T1 represents all to have apart from the line segment of destination P1, current location P2 and connection destination P1 and current location P2 the zone of the elliptical shape (fillet rectangle) of the distance of radius R 1.

In addition, Fig. 4 B is illustrated in the sphere of action T2 that the distance L 2 of current location P2 and destination P1 obtains when nearer.

With sphere of action T1 in the same manner, sphere of action T2 represents apart from destination P1, current location P2 and connects destination P1 and the line segment of current location P2 all has the zone of the elliptical shape (fillet rectangle) of the distance of radius R 2.

Wherein, the radius R 2 of the radius R 1 of Fig. 4 A and Fig. 4 B has radius R 1〉relation of radius R 2.

That is the sphere of action T2 when the sphere of action T1 when, distance L 1 is far away and distance L 2 are nearer has sphere of action T1〉relation of sphere of action T2.

Thus, owing to set the size of sphere of action according to user's purposes, thereby can alleviate user's pressure.

For example, can carry out such setting: be the error that allows 500m under the state of 10km in the distance destination, and be not allow the error of 500m under the state of 100m in the distance destination, but allow the error of 10m.

In addition, in Fig. 4 A, Fig. 4 B, be illustrated as an example of the sphere of action T1, the T2 that include current location P2 and destination P1 example.

About this point, the user who has set destination P1 moves along the direction from current location P2 to destination P1, the possibility that opposition side from from current location P2 to destination P1 moves is smaller, thereby also can the opposition side from current location P2 to destination P1 not set sphere of action.

In addition, in Fig. 4 A, Fig. 4 B, be illustrated as an example of sphere of action T1, the T2 of elliptical shape (fillet rectangle) example, but the shape of the sphere of action that sphere of action configuration part 113 is obtained being not limited to the elliptical shape shown in Fig. 4 A, Fig. 4 B (fillet rectangle), can be shape arbitrarily.

Fig. 5 A, Fig. 5 B, Fig. 5 C, Fig. 5 D, Fig. 5 E are the figure of another example of the sphere of action that obtained by sphere of action configuration part 113 of expression.

Shown in Fig. 5 A, user's moving direction is the direction from current location P2 to destination P1.

Therefore, can shown in Fig. 5 B, on the direction opposite with the moving direction of current location P2, not set sphere of action T3 yet.

In addition, shown in Fig. 5 C, also can not set elliptical shape (fillet rectangle), but be set in the sphere of action T4 of the fan shape of expanding from current location P2 to the direction of destination P1.

Therefore, the scope that the user can allow in the time of sphere of action being included in produce error and according to the position relationship of current location and destination and estimating user with the meaning of mobile scope.

In addition, in Fig. 4 A, Fig. 4 B, Fig. 5 B, Fig. 5 C, around current location P2 and destination P1, set sphere of action T1, T2, T3, T4, but be not limited to this, also can set sphere of action T5-1 on every side such as what Fig. 5 D was shown in current location P2.

In this case, the sphere of action of setting around current location P2 is the scope of setting according to current location P2 and destination P1, shown in Fig. 5 D, Fig. 5 E, set along with the far away and larger sphere of action T5-1 of the distance of current location P2 and destination P1, and set along with the nearer and less sphere of action T5-2 of the distance of current location P2 and destination P1.

Thus, can set according to user's purposes the size of sphere of action.

In addition, the shape of the sphere of action of setting around current location P2 as sphere of action T5-1, T5-2 is not limited to circle, also can be the shape (for example fan-shaped) of having considered user's moving direction.

In addition, the setting of sphere of action not only can utilize the distance of the positional information of the positional information of current location and destination, and can utilize out of Memory to set.

Table 1 expression is used for setting an example that imposes a condition of sphere of action.

[table 1]

About imposing a condition 2, for example when the location precision of the positional information that represents current location is relatively poor, might produce error in current location.

Therefore, setting in the situation of sphere of action according to the positional information of this current location and the positional information of destination, preferably set larger sphere of action, and enlarge the allowed band of the positional information that next time obtains.

In addition, about imposing a condition 3, such as, not necessarily being limited to through the path on the straight line that connects current location and destination faster in the situation in the translational speed of utilizing vehicle the user such as to move, be estimated as the user with mobile expanded range.

Therefore, when user's translational speed is very fast, preferably set larger sphere of action.

In addition, about user's translational speed, the variation of the positional information that for example can obtain according to positional information obtaining section 111 time interval according to the rules obtains.

In addition, about imposing a condition 4, in the less situation of the reduced scale of the map that is shown in display part 16 (dwindling map), as long as determining the approximate location relation of current location and destination, the user namely is enough to, and in the larger situation of the reduced scale of map (enlarged map), the detail location of customer requirements current location and destination relation.

Therefore, hour larger sphere of action can be set at reduced scale, when reduced scale is larger, less sphere of action can be set.

In addition, also can only be suitable for of imposing a condition in 1～4 and impose a condition, can also make up applicable a plurality of imposing a condition.

And, about the setting of sphere of action, can when obtaining the positional information of current location, positional information obtaining section 111 carry out, also can carry out at other arbitrary timing.

A setting example regularly of table 2 expression sphere of action.

[table 2]

About regularly 1, the setting of sphere of action can be carried out at regular intervals according to the timing that positional information obtaining section 111 obtains the positional information of current location.

At this moment, certain intervals can be when positional information obtaining section 111 obtains the positional information of current location, also can be when positional information obtaining section 111 obtains the positional information of current location of stipulated number.

On the other hand, shown in regularly 2～5, also can make the interval of the setting of carrying out sphere of action different.

About timing 2, when translational speed was fast, the variation of the positional information that the time interval is according to the rules obtained also increased.

Therefore, when translational speed is fast, preferably frequently carry out the setting of sphere of action.

Therefore, also can be as regularly making the interval of the setting of carrying out sphere of action different according to translational speed in the of 2.

In addition, about regularly 3, in the distant situation of distance destination, namely be enough to as long as can grasp the roughly direction of destination, thereby sphere of action self is set greatlyr, do not need frequently to carry out the setting of sphere of action.

Relative therewith, in the situation of the close together of distance destination, need to be grasped the detail location relation of current location and destination, and because sphere of action self is less, thereby preferably frequently carry out the setting of sphere of action.

Therefore, also can be as regularly making the interval of the setting of carrying out sphere of action different according to current location and the distance of destination in the of 3.

In addition, also can as regularly in the of 4 these regularly 2,3 being combined, make the interval of the setting of carrying out sphere of action different.

In addition, also can as regularly in the of 5 the location precision in the positional information of current location satisfy in the situation of the location precision more than the certain value, carry out the setting of sphere of action.

In addition, one that also can only be suitable in the timing 1～5 imposes a condition, and can also make up applicable a plurality of imposing a condition.

Turn back to Fig. 2, the positional information of the current location that the sphere of action that detection unit 114 is obtained sphere of action configuration part 113 and positional information obtaining section 111 obtain compares, and judges whether be present in the sphere of action in the positional information of having set the current location that obtains after the sphere of action.

Detection unit 114 determine whether be present in the sphere of action after, its result of determination is offered display control unit 115.

Display control unit 115 is carried out the demonstration control of display part 16 according to the result of determination of being supplied with by detection unit 114.

That is, display control unit 115 take the positional information that is judged to be current location by detection unit 114 in action in the scope as condition, the map that demonstrates this current location is presented at display part 16.

On the other hand, display control unit 115 take the positional information that is judged to be current location by detection unit 114 in action scope do not show that outward as condition this current location ground is not presented at display part 16 with map.

In the situation that do not show like this current location, preferred display control unit 115 makes at map and shows that the information of regulation replaces the current location that does not show.

As an example, the position that can before map is presented at this current location, just show (below, be called " current location before this ").

In addition, also can show connect optional position on the line segment of positional information of the positional information of this current location and current location before this at map.

In addition, also can be according to sensor section 20 detected sensor valuess, obtain the self-navigation information of the expression direction that moves of user and mobile distance, and show the position that the positional information according to this self-navigation information and current location before this obtains at map.

Signal conditioning package 1(CPU11 more than has been described) functional structure.

Below, illustrate that the navigation of signal conditioning package 1 execution with this functional structure is processed.

Fig. 6 is the process flow diagram of the flow process processed of expression navigation, and Fig. 7 is the process flow diagram of the flow process processed of destination setting that the expression navigation is processed.

With reference to Fig. 6, at step S1, CPU11 begins the GPS location.

That is, CPU11 is by the reception of gps antenna 191 beginning gps signals.

Then, at step S2, destination setting section 112 carries out the destination that destination setting processes to set the user.

In addition, the details of processing about destination setting will describe in Fig. 7 of back.

Then, at step S3, sphere of action is obtained according to the position and the destination that are shown on the map in sphere of action configuration part 113.

Then, at step S4, positional information obtaining section 111 obtains the positional information of the current location of expression signal conditioning package 1 according to gps signal.

Then, at step S5, detection unit 114 judges that the positional information that obtains by step S4 is whether in the sphere of action that obtains by step S3.

At this moment, when in the scope in action, display control unit 115 makes the map at display part 16 show the current location (step S6) corresponding with the positional information that obtains by step S4, makes processing enter into step S7.

On the other hand, when outside the scope in action, display control unit 115 makes and do not show current location on the map of display part 16, makes to process to enter into step S7.

Then, at step S7, CPU11 judges whether the destination has change.

In this was processed, CPU11 for example by the operation of input part 18 accepted users, judged thus whether the destination has change.

At this moment, when in the destination change being arranged, CPU11 makes to process and enters into step S2, and when not changing in the destination, CPU11 makes to process and enters into step S8.

At step S8, CPU11 determines whether and arrives the destination.

In this is processed, whether CPU11 is for example consistent according to the positional information of the destination of setting at step S2 and the positional information of the current location that obtains at step S4 (positional information of the current location that perhaps demonstrates at step S6), determines whether to arrive the destination.

When arriving the destination (consistent time), CPU11 finishes navigation to be processed.

On the other hand, when not arriving the destination when inconsistent (), CPU11 makes to process and enters into step S3, the repeatedly processing of step S3～step S8.

Then, with reference to Fig. 7, in destination setting was processed, at step S11, display control unit 115 made at display part 16 and shows map.

Then, at step S12, display control unit 115 makes the map scroll that shows at display part 16 or amplifies to show according to rolling operation or the amplifieroperation accepted by input part 18.

Then, at step S13, destination setting section 112 judges whether the reduced scale of the map that shows by amplifieroperation at step S12 reaches more than the setting.

At this moment, under the reduced scale of map reached situation more than the setting, at step S14, the center that destination setting section 112 will amplify after showing was set as the destination.

On the other hand, under the reduced scale of map did not reach situation more than the setting, CPU11 made to process and enters into step S12.

Then, at step S15, destination setting section 112 determines whether that the map to being exaggerated demonstration has carried out rolling operation.

At this moment, about for the rolling operation that is exaggerated the map after the demonstration, estimation is that the destination is finely tuned, thereby destination setting section 112 is modified to the destination center (step S16) of the map after the fine setting, finishes destination setting and processes.

On the other hand, in the situation that do not accept rolling operation after being exaggerated demonstration, CPU11 finishes destination setting to be processed.
